New rumor from the Chinese supply chain says that new iMacs with Ivy Bridge CPUs are going on sale in July.
I just bought a new Core i7 iMac in January. According to a new rumor from How To Arena (via Apple Insider) it will be outdated in July. The new 2012 iMac will be using new 22nm Ivy Bridge Core i5 and Core i7 CPUs. The first Ivy Bridge based Apple computer is supposed to be a 15-inch MacBook Pro that is rumored to be coming in April.
The new iMacs are possibly also thinner than the current generation.
The important factor for a high performance iMac is the SSD. So I am not that concerned and will still be happy with my 2011 Core i7 iMac with SSD configuration.
